The red box must way more. Gravitational potential energy is the product of a an objects mass times the acceleration due to gravity (which is constant on earth) times its height. Since the objects are on the same shelf they are at the same height, and since gravitational acceleration is constant as long as we stay on planet earth, then the mass is the only possible thing that could have changed. This means that the red box must weigh more than the blue box.
Average speed = distance / time
Average speed = 90 km / 0.5 hrs
Average speed = 180 km per hour

Reaction rates are affected by reactant concentrations and temperature. this is accounted for by the c</span>ollision model.
